a question about appserver

zarzor_2010 · 09-09-2010, 09:00 PM

Hi all
I have a strange problem

I have a computer in the university and I have root access to this pc.
Iam trying to install Cblas library on it. But it gives me a starnge error

/usr/local/atlas is read only file system.

I tried doing mount -l
and it gave me that

appserver1:/export/d1/Linux/doe on /usr/local type nfs4 (ro,sec=.......)

I think what it means that the main server directory is mounted to /usr/local and it is read only.

So, how can I fix this problem to separate the two and make my /usr/local separate

Thanks in advance

Hi,

Are you 100% certain that none of the stuff under the current /usr/local
will be required? Or that it's ok with your institution if you made local
copies of whatever is there?

If no other users on that machine will need the app you could always
just install it in your home.

Cheers,
Tink

No, Iam the only one who uses this PC. and I do not think that I will need the data in /usr/local

But how can I install the application under my home directory? it needs to add static library to /usr/local/

Thanks for your help

If you have data under /usr/local your varsity has
a weird layout :} for its network file-systems.

I have no idea how Cblas works its install, but if you compile
it from source you can just tell it to install to your home; and
you can then add it's lib-path to LD_LIBRARY_PATH in your bashrc.

Thank you so much

I tried umount /usr/local to unmount my local folder from the srver folder

But I have another question please. is the umount i used is permenant. or it will come back after I restart my pc.

If it is not permanent, How I can make it permanent?

Thanx alot for your help

Depends on how it's being mounted. Most likely one of
two alternatives:
a) Via a line in /etc/fstab
b) Using autofs, check /etc/auto.net or /etc/auto.misc
(in doubt check auto.master whether it includes any
other files in your distro).

In either case you just need to comment the line that
pertains to the share you're seeing.

Cheers,
Tink

Thank you so much for your reply

However I did not find the line that mount this appserver. Here is my auto.master

PHP Code:



net -hosts 
/misc /etc/auto.misc 
/- /etc/auto.direct 
/home ldap://ldap4/automountMapName=auto_home,dc=doe,dc=carleton,dc=ca -fstype= 
+auto.master

Here is my /etc/auto.net

PHP Code:



key="$1" 
 
# add "nosymlink" here if you want to suppress symlinking local filesystems 
# add "nonstrict" to make it OK for some filesystems to not mount

        END     { if (!first) print "\n"; else exit 1 } 
        ' | sed 's/#/\\#/g'

Here is my /etc/auto.misc

So what about auto.net & fstab?

zarzor_2010 · 09-17-2010, 08:36 AM

Thank you all for trying to help me of this issue.

here is my /etc/fstab

Sorry, meant auto.misc. But that .net doesn't look like any autofs
config file I've ever seen - it's a shell script of sorts?

What OS & version are you running?

/etc/auto.misc is

follow this link to get autofs details

http://www.redhat.com/docs/manuals/l...nfs-mount.html

zarzor_2010 · 09-17-2010, 10:05 AM

I have checked the autofs files in the univ PC. (/etc/auto.master, /etc/auto.misc, /etc/auto.net) and there is no entery for that file

appserver1:/export/d1/Linux/doe on /usr/local type nfs4 (ro,sec=.......)

is there a way to check a log file on the univ linux to see from where it is got mounted?

Thanks
Mina
